ok, i just got done with my b16 swap i'm very excited, and vtec is cool stuff. My problem is that I don't have the o2's hooked up, I got one hooked up, but the other is just sitting there, right now the one that i have hooked up, is the white one, i got it going into my stock harness, (90 crx si) and it goes down to my ecu, the green 02 sensor hsa the hasport subharness connected to it, and it's running inside my car, but it's not hooked up yet. Now this is where it gets tricky, I've been told by a friend that the 02's have to be switched, or something. So exactly what pin does the white o2 sensor go to?? Does the white one go to the pin c16?? Cause that's where the orignal oen went to(going off of hasports information) and they say to fill pin c8 with the green 02 sensor. Now, I can do this, no problem but, is that the proper way to do it, Or is it supposed to be ther other way around. Thanks for listening and all your help!

 

Well it actually depends more on placement to which o2 plug goes where, each sensor is supposed to be paired in a certain set of primaries. so if you have the green plug sensor in the white plug location, you would need to wire it so it goes to the pin for the white plug. (the sensors themselves are actually reading the same, just in diffferent locatins) Hope you can understand what I'm trying to say

 

ok, i'm not to sure what you said, but i just went out and checked, and the green o2 sensor is on the top. and the white o2 sensor is on the bottom (stock jdm manifold) the b16 is from the integra if that helps, and the ecu is a pr3. So where should the white plug one go? Which ecu pin should it go to?

 

Green plug goes to c 8....I'm almost 100%sure
